The ReefBox Posted October 5, 2021 Share Posted October 5, 2021 So I’ve been running my trident for over a year and half. Lately (past 4-5 months) the thing reads off, doesn’t change at all or said bad sample range. I’ve tried cleaning the vial, recalibration group with calibration fluid and manual calibration. Still reads off. Comparison with salifert tests todAy which are all new. Last manual test using those numbers registers below the comparison Alk Trident 8.7 Salifert 9.25 CA Trident 388 Salifert 410 Mag Trident 1459 Salifert 1470 manual calibration ca. 0 out of range alk 8.66 mg 1524 Quote Link to comment Share on other sites More sharing options...
half-astronaut Posted October 5, 2021 Share Posted October 5, 2021 Neve you sent the unit off for it's periodic maintenance? The instructions say to keep the box for maintenance shipping, but I never hear anyone talk about the process. Quote Link to comment Share on other sites More sharing options...
goldenbasketreef Posted October 5, 2021 Share Posted October 5, 2021 Is the difference between Salifert and Trident result always the same or different spread every time you did the comparison test? My trident always give me different spread compare to salifert, the spread never consistent always different number each time I compare. Lately I have been using tank water to calibrate the Trident. I test will Salifert and enter the number for calibration number and let the Trident run calibration using tank water. So far it has been consistent now, not much different between Salifert and Trident result for Calcium and Magnesium. But Alk always +2 with Salifert, Trident Alk test result always lower compare to Salifert in my case. Quote Link to comment Share on other sites More sharing options...

My trident number for alk is always lower, ca is always lower too then I get random out of range when I calibrate. I calibrated with actual tank water this time and numbers came out the same as number I entered. Will see what happens at six pm Quote Link to comment Share on other sites More sharing options...

pdxmonkeyboy Posted October 6, 2021 Share Posted October 6, 2021 My trident alk and cal readings are always a bit lower. I was having some weird readings and it went away when I cleaned the vial. I also made sure the drain and input lines are the same length.. they were not when I initially set it up. Quote Link to comment Share on other sites More sharing options...
The ReefBox Posted October 7, 2021 Author Share Posted October 7, 2021 Ok so on the advice of several reefers and shops I embarked on a full breakdown and cleaning of trident. I removed the cover unplugged all of the lines from the central hub and blew each line out with compressor. I cleaned the glass test vial with a q-tip. I then disconnect feed and waste line and blew them clear. Checked all the fittings and reassembled the trident. I have restarted the trident and waiting for the initialization to complete then I will prime all the lines and reset reagents and waste container. I feel paying $200 for routine maintenance through Neptune is crazy every 18 months (recommend interval). Short of needing new tubing or broken parts I’m trying this first. I’ll report what I come up with after it’s back online and testing 1 Quote Link to comment Share on other sites More sharing options...
titus'reef Posted October 8, 2021 Share Posted October 8, 2021 (edited) You did a lot of work for this trident. I agree with the $200 for something we can do, is too much. Very curious for the results. Edited October 8, 2021 by titus'reef Quote Link to comment Share on other sites More sharing options...
The ReefBox Posted October 8, 2021 Author Share Posted October 8, 2021 So far the first test is based off manual calibration using tank water after all work completed on Trident I used manual tests using Salifert The manual tests are CA 410 ALK 8.9 MAG 1450 first test at 6pmnotice CA and MAG did not change from manual input. I’ll see what my midnight test brings Quote Link to comment Share on other sites More sharing options...
titus'reef Posted October 9, 2021 Share Posted October 9, 2021 That doesn’t look that bad. If it stays stable it should be good. Quote Link to comment Share on other sites More sharing options...
